Teachers’ assessments of children aged eight predict life satisfaction in adolescence

The objective was to investigate how teachers’ assessments of children predict life satisfaction in adolescence. This is a
prospective cohort study on the population-based Northern Finland Birth Cohort 1986 (n = 8,959). Information was gathered from parents, teachers and adolescents using questionnaires at the age of 7, 8 and 15.
Response rates were 80–90%. Emotional and behavioural problems were assessed with Rutter Children’s Behavioural Questionnaires
for teachers (RB2) and parents (RA2) during the first grade at age 8. At adolescence, self-reported life satisfaction was
measured with a question including five response alternatives. According to teachers’ assessments, 13.9% of the children had
high emotional or behavioural problems (RB2 ≥9). These assessments predicted life dissatisfaction in adolescence (OR_crude = 1.77; 95% CI 1.43–2.20) in several models including also health behaviour and use of psychotropic medicine. However, introducing
all the significant variables in the same model, RB2 lost its significance (OR = 1.28; 0.96–1.70), but good school achievement
assessed by teachers was still a significant predictor. Life satisfaction in adolescence was associated with a variety of
favourable concurrent factors. In conclusion teachers’ assessments of children during the first school year predicted life
satisfaction in adolescence. In mental health promotion, teachers’ early assessments should be utilized for the benefit of
children.
